Abstract
The Potential Alternative Antibacterial Activity Of Falcata (Falcataria falcata) Leaf Methanolic Extract Against Staphylococcus aureus And Escherichia coli Laliefe B. Arnan; Katherine Joy S. Escueta; Nor Rashida P. Rashid; Elyca M. Tacbobo; Queenie Rose M. Tinoy Degree: Bachelor of Science in Pharmacy Thesis Adviser: Junnin Gay L. Garay, RPh, CPh, MS Pharm Falcata is a plant that can be found in the Philippines and is used for the production of wood veneer and plywood. While in Indonesia, it is used as traditional remedy for malaria (Budiarti et al. 2020). They belong to the Fabaceae family, a family known for having great antibacterial effects (Gamo et al. 2015). This study used a percolation extraction method and the percentage yield is calculated to determine the yield from the falcata extract. Disc diffusion method is used for susceptibility testing and determining the zone of inhibition for the different groups. The CLSI guidelines for Staphylococcus aureus and Escherichia coli will be used to determine the antibacterial effect of the extract, in terms of resistance, intermediate, and susceptible results. From the results, the percentage yield of the methanolic crude leaf extract of Falcataria falcata is 2.67%. Leaves from the Falcataria falcata plant were extracted and tested against bacteria. The extracts showed promise in inhibiting the growth of Staphylococcus aureus and Escherichia coli bacteria, with 75% concentration as being more effective. However, these bacteria showed some resistance to all extract concentrations: S. aureus (90% - resistant, 75% - intermediate, 50% - resistant, 25% - resistant); E. coli (90% - resistant, 75% - resistant, 50% - resistant, 25% - resistant). Further study is needed to determine the exact antibacterial properties of the plant.
